This invention relates to a water heater, and more particularly to such a heater adapted to be utilized in conjunction with a vehicle driven by water-cooled internal combustion engines.

A primary object of this invention is the provision of an improved heater adapted automatically, to heat the water in the radiator of an internal combustion engine, when the same falls below a predetermined temperature, in order to insure relatively easy starting of the vehicle.

Another object of this invention is the provision of such a heater which may be utilized when the motor of the vehicle is not running, by plugging the same into any conventional electrical circuit.

A still further object is the provision of such a heater which may be utilized to heat the cab or cockpit of the vehicle with which it is associated, when the engine is not in operation.

Qther objects will in part be obvious and in part be pointed out hereinafter.

Additional objects reside in the combinations of elements, arrangements of parts, and features of construction, all as will be more fully pointed out and disclosed in the accompanying drawings, wherein there is shown a preferred embodiment of this inventive concept,

In the drawings:

Figure 1 is a, side elevational view of one form of apparatus embodying features of this invention.

Figure 2 is a sectional view taken substantially along the center line of certain portions of the operating mechanism.

Figure 3 is a sectional view takenalong the line 33 of Figure l as viewed in the direction indicated by the arrows.

Figure 4 is an end elevational View of the device taken substantially along the line 4-4 of Figure 2.

Figure 5 is a sectional view taken substantially along the line 55 of Figure 2 as viewed in the direction indicated by the arrows.

Figure 6 is a sectional view taken substantially along the line 66 of Figure 2 as viewed in the direction indicated by the arrows, and

Figure 7 is a sectional View taken substantially along the line 'l! of Figure 1, as viewed in the direction indicated by the arrows.

Like reference numerals refer to like parts throughout the several views of the drawings.

Having reference now to the drawings, there is generally indicated at H), in Figure 1, a housing or casing within which is positioned a cylindrical sleeve I I, adapted to be secured to the wall thereof as by bolts [2 passed through flanges I3. Sleeve H is provided with an inlet l4, and an outlet I5, to which are secured suitable conduits (not shown) adapted to pass water from the radiator of the vehicle with which the device is associated through the sleeve, which is provided with a plurality of interior-1y disposed'apertured bafiles l6, and over an electrically actuated immersion heater ll of any desired type (see Figures 2 and 5).

Sleeve ll is provided with end caps l8 and I 8a, secured in position as by bolts l9 and 20, respectively, passed through suitable apertures in flanges 2| and 22 formed at the extremities of sleeve H.

Immersion heater I1 is secured in a block 25 mounted on the interior of end cap l8, and is connected in electrical association to a conduit 26 which extends from a lock nut 21 secured to a suitable threaded flange carried by cap 18, to a switch box 23. Switch box 28 contains switching mechanism of any desired conventional type and is supplied with power through a conduit 29 provided at its extremity with a plug (not shown) adapted to be connected to any suitable source of power. The switch mechanism is adapted to energize the heater in accordance with the temperature of the water in the radiator of a vehicle, when actuated by a thermostat (not shown) positioned in the radiator, and connected to the switch box as by means of a conduit 36. I

From the switch box 28 a conduit 3! leads to an electric motor 32 of any desired conventional type, secured within the casing HI and provided with a drive shaft 33 having a pulley 34 mounted thereon. A drive belt 35 surrounds pulley 34 and extends to a pulley 36 mounted on a shaft 31, carried by a frame 38 secured to the exterior of end cap 18a. The shaft 3? extends through a suitable packing gland 39 seated in an aperture in end cap l8a to the interior of sleeve II, where its inner extremity is carried in a journal 40 centrally positioned in a supporting member 4| secured to an apertured propeller cone 42, the apertures therein being indicated at 43. Mounted on the shaft 3'! within the propeller cone 42 is a propeller 44 of any desired configuration, adapted to circulate the water over the immersion heater ll, from the inlet [4 to the outlet [5.

Now from the foregoin the operation of the device should be readily understandable. The casing to is secured at any desired point within the vehicle, as for example, under the hood, or in the cab, or the like, and the inlets and outlets i4 and I5 suitably connected to the vehicle engines radiator. When the vehicle is not in operation, the conduit 29 is suitably connected to any desired source of electrical power, and when the temperature of the water in the radiator falls below a predetermined point, the thermostat therein, through conduit 30, closes the switch mechanism in the switch box 28 to energize immelsion heater l7 and simultaneously to drive electrical motor Th motor 32 through the belt and pulley connections 34, 35 and 36 above described drives the propeller 4 to circulate water from the cold radiator over the heater H, heat the same and return it to the radiator. When the temperature of the water within the radiator has reached a desired predetermined point, the thermostat above mentioned serves to throw the switch mechanism 28, resulting in the discontinuation of the operation of motor and the deenergization of immersion heater [1.

It will now be seen that there is herein provided a heater for any desired type of vehicle utilizing a. water cooled internal combustion engine, which accomplishes all the objects or" this invention and others including many advantages of great practical utility and commercial importance, which insures quick starting motor in cold weather, immediate lubrication of the operating parts of the engine when the same is started, and a. material reduction of the time required for heating up the motor of the vehicle in order to achieve maximum operating efficiency.

As many embodiments may be made of this inventive concept, and as many modifications may be made in the embodiment hereinbefore shown and described, it is to be understood that all matter herein is to be interpreted merely as illustrative and not in a limiting sense.
